Did you manage that one radius of a circle?

The radius of a circle is a line from the centre of the circle to a point on the side.

Let R be the radius of a circle one quarter of which measures C.

In geometry, the radius of a circle or sphere is the shortest connection between the center and the boundary.

The method hinges on the observation that the radius of a circle is always normal to the circle itself.

The geometrical solution to this is for all wheels to have their axles arranged as radii of a circle with a common centre point.

The radius of a circle is perpendicular to the tangent line through its endpoint on the circle's circumference.

Radius of a circle of area π km.

This is the radius of a circle that would fit into the shape of the edge of the ski if viewed in plan-view.

The length of a degree of longitude depends only on the radius of a circle of latitude.

To compute the radius of a circle going through three points P, P, P, the following formula can be used:

These rings may be installed axially (horizontally along the center point of an axis) or radially (externally along the radius of a circle).

The circumradius of this square (the radius of a circle drawn through the square's vertices) is half the square's diagonal, and equals .

It is defined as the radius of a circle, centered about the mean, whose boundary is expected to include the landing points of 50% of the rounds.

The body is then placed on a wiralli (crossed sticks that form the radii of a circle) and an inquest is held to determine cause of death.

Thus the MSE results from pooling all these sources of error, geometrically corresponding to radius of a circle within which 50% of rounds will land.

Disc area can be found by using the span of one rotor blade as the radius of a circle and then determining the area the blades encompass during a complete rotation.

For other curved lines or surfaces, the radius of curvature at a given point is the radius of a circle that mathematically best fits the curve at that point.

For external points, the power equals the square of the radius of a circle centered on the given point that intersects the given circle orthogonally, i.e., at right angles (Figure 2).

For instance, linearly increasing the radius of a circle in Euclidean space increases its circumference linearly, while the same circle in hyperbolic space would have its circumference increase exponentially.

The area designation can be the letter S, to specify the sides of a rectangle (separated by the letter X); or the letter R, to specify the radius of a circle.

More importantly, one may define a function on a set, such as "radius of a circle in the plane" and then ask if this function is invariant under a group action, such as rigid motions.

The reason is that the radius of a circle would be measured with an uncontracted ruler, but, according to special relativity, the circumference would seem to be longer because the ruler would be contracted.

Using the intersecting chords theorem (also known as power of a point or secant tangent theorem) it is possible to calculate the radius of a circle given the height and the width of an arc:

In the following lines, represents the radius of a circle, is its diameter, is its circumference, is the length of an arc of the circle, and is the angle which the arc subtends at the centre of the circle.
